Certification marks and hazardous-area classifications: cross-market equivalences
Canonical, always-current version: https://referencesource.org/certification-standards-equivalence/ Machine-readable: https://referencesource.org/certification-standards-equivalence/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-11
- Stale after: 2027-08-11 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 200
Which product-safety certification mark applies in which market, who administers it and under what law (CE, UL, CSA, CCC, PSE, KC, BSMI, RCM, EAC, NOM, INMETRO and others), and how the two hazardous-area classification systems map onto each other: NEC Class/Division designations against IEC/ATEX Zone designations, gas group cross-references (NEC Group A-D against IEC IIA-IIC), temperature-class mappings, and the protection-concept codes (Ex d, AEx e, intrinsic safety) with the US, Canadian and IEC standards behind each. Answers 'is a CB certificate accepted in the US', 'what is the ATEX equivalent of Class I Division 2', and 'which mark is compulsory in China' — questions where the honest answer is often that there is no direct equivalent, and saying so is the value.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
Factual compilation with source citations. Facts about which mark applies where and how classification systems map are taken with short attributed quotes linking back to the published guide or page. No standard text is reproduced.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
